The book-shaped cart is placed with the side facing up, and the book-shaped cart is transported to the vicinity of the molding drum. Next, the operator takes out the strips one by one from the upper shelf as necessary, turns them upside down, and attaches them with the side facing up. After it is placed down, it is supplied to the molding equipment servicer and the empty shelf is flipped up from a horizontal position to an inclined position.

However, if workers carry out the work of supplying such strip-like members to ships, there are problems in that the work efficiency is low due to the heavy weight of the strip-like members, and the workers are forced to do heavy labor. Ta.

SUMMARY OF THE INVENTION An object of the present invention is to provide a belt-shaped member feeding device that can automatically perform a belt-shaped member feeding operation with high efficiency.

This purpose is to provide a traveling carriage movable in the width direction of the strip member, a traveling means for traveling the traveling carriage, a swivel base supported by the traveling carriage so as to be rotatable about a vertical axis, and a rotating platform capable of rotating around a vertical axis. A turning means for rotating the turning table, a lifting table supported by the turning table so as to be able to rise and fall, and a lifting means for raising and lowering the lifting table.
A distant relative can be achieved by providing a horizontal suction rod that is supported at its base end on a lifting platform and that can suction the upper surface of the strip member, and a rotation means that rotates the suction rod by half a rotation around the central axis. .

Suppose that a belt-shaped member is placed on the shelf of a cart. Next, when such a strip member is taken out from the shelf, turned upside down, and then supplied to the servicer of the molding equipment,
First, the traveling means and the elevating means are operated to move the traveling carriage in the width direction of the strip-like member, and at the same time raise and lower the elevating platform, and move the suction rod from the standby position to just above the strip-like member to be suctioned. Next, after holding the strip member by sucking the upper surface of the strip member with the suction rod, the elevating means is operated to raise the strip member, the suction rod, and the lifting platform as one unit. Next, the rotation means is activated to rotate the suction rod by half a rotation around the central axis to turn the strip member upside down, and
The turning means is operated to turn the turning table, the lifting table, and the suction rod until the strip member reaches directly above the servicer. If the belt-shaped member cannot reach directly above the servicer due to the installation location of the servicer, at least one of the traveling means or the elevating means is actuated to cause the traveling cart to travel or to raise and lower the elevating platform. , move the strip member directly above the servicer. Next, the strip member is separated from the suction rod and supplied to the servicer. Then, by repeating the above-described operation, the belt-like members are turned upside down one after another from the shelf of the cart and supplied to the servicer. In addition, in the present invention, it is also possible to supply the strip member to the servicer without operating the rotation means, that is, without turning the strip member upside down.

A pair of posts 38 extending vertically are erected on the upper surface of the rotating body 37 and spaced apart from each other in the front-rear direction, and a rail 39 extending along the posts 38 is provided on the right side of these posts 38 . In addition, a traveling trolley 24 is located at the center of this rotating body 37.
A rotating shaft 40 passing through is fixed. The above-described rotating body 37, post 38, rail 39, and rotating shaft 40 collectively constitute a swivel base 41 supported by the traveling carriage 24 so as to be rotatable around a vertical axis. A rotary actuator 42 as a turning means is attached to the lower surface of the traveling carriage 24, and this rotary actuator 42 is connected to the rotating shaft 40 and turns the turning table 41 by a predetermined angle.

Reference numeral 45 denotes an elevating table that is supported by the swivel table 41 so as to be movable up and down, and this elevating table 45 has slide bearings 46 that are slidably engaged with the rails 39, respectively. A bracket 51 is attached to the left side surface of the post 388, and a motor 52 is fixed to this bracket 51. The post 388 also has a pair of bearings 53 spaced apart vertically.

As a result, when the motor 71 operates, the suction rod 66 rotates by half a rotation around the central axis, so that, for example, the suction pad 68, which was facing downward, now faces upward. In addition, 80 is the rotary actuator 1
3.42, control means for controlling the operation of the motor 28.52.71.

1 Next, the operation of one embodiment of the present invention will be explained.

Now, the roller conveyor 8 is waiting at the receiving position B,
It is also assumed that the suction roller 6 is on standby at a standby position shown by the solid line in FIG. 1, and that the cart 1, on which the shelf 2 is fully loaded with the strip members T, has been carried into a predetermined position. Next, the motor 52 is activated to rotate the T-screw shaft 54, and the lifting platform 45 and suction rod 66 are lowered integrally along the rail 38 by a predetermined distance. Next, when the motor 29 is operated to rotate the sprocket 31, the traveling carriage 24 moves rearward while being guided by the rails 23. Then, a sensor (not shown) installed in the suction londro 6 is connected to the trolley.
When the number 1 shelf 2 is detected, the operation of the motor 29 is stopped.

Next, the motor 52 is operated again to lower the lifting platform 45 and the suction rod 66, but the operation of the motor 52 is stopped when a sensor (not shown) detects the top shelf 2 in a horizontal position. Next, the motor 28 is operated again to move the traveling carriage 24 and the suction rod 66 in the width direction of the strip member T, here, toward the rear. The movement of this traveling cart 24 is controlled by the suction rod 66.
When a sensor (not shown) fixed to detects the front side end of the front row of strip members T loaded on the shelf 2, the sensor stops. Next, the motor 28 is operated again for the time set by the timer. As a result, the traveling trolley 24
is retreated by a distance half the width of the strip member T, and the strip member T
The suction rod 66 extending parallel to the front row reaches just above the center in the width direction of the strip member T located in the front row. Next, after operating the motor 52 to lower the suction pad 86 until the suction pad 68 is pressed against the upper surface of the strip member T, the switching valve is switched to connect the suction pad S8 to the vacuum source. This results in
Each suction pad 68 adsorbs the surface (upper surface) of the strip member T, and the strip member T is transferred from the shelf 2 to the suction rod 66. Next, the motor 52 is operated again to raise the lifting table 45, suction rod 66, and band member T integrally by a predetermined distance. Next, the motor 71 is operated to rotate the suction rod 66 that holds the strip member T by half a rotation around the central axis of the suction rod 66 . As a result, the suction pad 68, which was facing downward, now faces upward as shown by the imaginary line in FIG.
The strip member T is attached with the surface facing downward. Next, motor 2
9 to move the traveling carriage 24 to its forward limit. Next, the rotary actuator 42 is operated to rotate the swivel base 4.
1. The lifting platform 45, the suction rod 66, and the strip member T are rotated integrally around the rotating shaft 40 from the position shown by the solid line in FIG. 1 toward the position shown by the imaginary line. During this rotation, by operating the cylinder 67 to project the piston roller 8, the distance between the strip member T and the suction rod 66 in the vertical direction is increased, and the suction rod 66 or the strip member T is connected to the roller conveyor. 8 from interfering with each other.

At this time, the suction pad 68 and the strip member T are in close contact with each other due to the adhesive applied to the surfaces, but if you try to transfer the strip member T to the roller conveyor 8 in this state, the strip member T may not come off the suction pad 69, resulting in a transfer error. For this reason, in this embodiment, the switching valve is switched to connect the suction pad S8 to the compressed air source, and air is gently blown out from the suction pad 69 to reliably remove the strip member T from the adhesion of the suction pad 69, as described above. This prevents such situations from occurring. At this time, the suction pad 68 of the strip member T is arranged apart from the suction pad 69 in the width direction of the strip member T as shown in FIG. , when the suction roller 6 rotates to the position shown by the imaginary line in FIG.
On the other hand, the strip member T placed on the suction pad 68 is a roller conveyor.
Reach the 7th straight second. Next, the piston rod 8 of each cylinder 67 is bowed to lower the finger-like member T, but during this downward movement, the band-like member T is transferred and supplied from the suction rod 66 to the roller conveyor 8. Next, the rotary actuator 42 is actuated to turn the swivel base 41. Lifting platform 45
Then, the empty suction iron f (6) is rotated and returned to the standby position. After moving,
The strip member T is carried out forward while being centered by the centering mechanism 515. The strip member T thus carried out is then placed around a forming device, for example a forming drum. next,
The roller conveyor 8 is again swung from the supply position A to the receiving position B by the rotary actuator 13. When the supply of the front row strip members T loaded on the top shelf 2 is completed in this way, the same operation as described above is repeated to supply the center row strip members T, and then the rear row strip members T. It is supplied to the servicer 5 one after another. Note that after the finger-like members T in the rear row are taken out from the shelf 2, the suction rod 66 is hooked onto the empty top shelf 2 and flipped upward.

Such operations are performed sequentially, and the strip members T loaded on the shelf 2 are taken out one after another from the upper stage side to the lower stage side and supplied to the servicer 5.

In the above-mentioned embodiment, since the strip members T were stacked on the shelf 2 with the pasted side facing up, the strip members T were turned upside down in the chamber after being taken out. If the strip member 6T is, for example, a carcass ply or a belt ply in which cords inclined in the same direction are embedded, the belt-like member 6T is alternately fed as it is taken out and inverted, and then placed on the forming drum. The plies may be wrapped so that the cords cross each other. Further, in the above embodiment, the strip member T is connected to the suction pad 6 connected to the vacuum source.
8, but in the present invention, the strip member T in which the steel cord is embedded may be attracted by a permanent magnet or an electromagnet.

As explained above, according to the present invention, it is possible to mechanically feed the strip member without relying on the labor of the worker, which improves work efficiency and improves the feeding work. Automation is also possible.
